Product Comparison
Aluminum PCB has the following advantages over other products in the same category.
  • v s
Application Scope
Aluminum PCB developed and produced by A-TECH is widely applied to many industries and fields. It can fully meet the diversified needs of customers.A-TECH always adheres to the service concept to meet customers' needs. We are committed to providing customers with one-stop solutions that are timely, efficient and economical.
Company Advantages
1. A-TECH pcb surface finish has been designed by considering its systems. These systems include machine control system, PLC system, variable speed drive and servo system.
2. Every detail of pcb surface finish exhibits exquisite workmanship.
3. pcb surface finish is made by silver coating pcb ,which allows it to have the property of lead free hasl pcb.
4. The product plays a critical role in various mechanical devices with moving parts, making it possible for the machine to run smooth with high efficiency.
5. People can rest assured that the product does no harm to the human body because the ammonia refrigerants used release no toxic substances.


HAL(Lead Free), the full name is Hot Air leveling with Lead Free. Compared with HASL, the main difference for HAL(Lead Free) is the element of material which do not contain Lead(Pb), so it’s RoHS Compliant and it’s much more popular and widely used in PCB manufacturing.

HAL(Lead Free) requires higher run temperatures for lead free solder and longer contact time, the production cost for HAL(Lead Free) is slightly higher than HASL(Tin/Lead).

The manufacturing process of HAL(Lead Free) is similar to HASL(Tin/Lead), the circuit boards will be submersed in molten solder(Lead Free). This solder will cover all the exposed copper surfaces. Upon retraction from the solder, high pressure hot air is blown over the surface through air knives, this levels the solder deposit and removes the excess solder from the surface of printed circuit boards.

The typical thickness of HAL(Lead Free) is 1-40um and the shelf life is 12 months.



The advantages of HAL(Lead Free) surface finish

● Good solderability / wettability
● RoHS Compliant
● Good reflow properties
● Large processing window is allowed
● Multiple thermal excursions
● Can be widely used



The disadvantages of HAL(Lead Free) surface finish

● Uneven surface
● Not suitable for PCBs with fine pitch
● Thermal shock
● Solder bridge
● Plugged or Reduced plated through holes



A-TECH have HAL(Lead Free) surface finish in house, It’s basically the highest proportion of finish used for circuit boards without fine pitch or high density layout. We don’t have any additional cost for HAL(Lead Free) surface finish.
